Another 39 Australian women have had faulty French breast implants rupture, according to the nation's medical goods regulator.

The Therapeutic Goods Administration (TGA) has published its latest update on its investigation into breast implants from French company Poly Implant Prothese (PIP).

Since February, the TGA received another 39 confirmed reports of ruptured implants and two unconfirmed reports, bringing the number of confirmed cases in Australia to 490.

More than 300,000 women around the world were fitted with PIP implants.

PIP's founder and chief executive, 73-year-old Jean-Claude Mas, has admitted filling the implants with an unapproved homemade recipe made of industrial-grade silicone gel.

The TGA's update yesterday included advice from European Commission's Scientific Committee on Emerging and Newly Identified Health Risks, which has comprehensively examined the issue.

The committee found there was no reason to remove the implants from women unless they were experiencing "significant anxiety" about having PIP implants.

The committee also said there were reports the implants ruptured earlier in their lifespan than other implants.

"While there are differences in rupture rates there is no reliable evidence that ruptured PIP implants create a greater health risk than a ruptured silicone breast implant from another manufacturer," the committee’s report stated.

"There is currently no convincing medical, toxicological or other data to justify removal of intact PIP implants as a precautionary approach."
